Jobs up and jobs down
Just one data point, but it may explain some things. Why are the numbers so bad for last year when it just does not seem so looking around Downtown and environs. Looks like the suburban counties came in pretty low this year for this county-level (jobs by place of work) data. This is the same data that has had Washington county among the fastest job gainers in frequently over the last decade. But this year, absolutely flat (0.0%) employment growth in Washington County, while Allegheny County had growth. So best not to forget that regional metrics are indeed derived from what is happening across the region, not just in its core.
The table linked previously only has data for the largest counties in the US, so only some of counties in the Pittsburgh MSA. For the larger counties in the region the December 12 to December 13 employment change (%): Allegheny +0.4%, Butler -0.4%, Washington 0.0%. Westmoreland -1.3%
